Quercetin, Insulin, Diabetes, Rats, Alloxan


Background: Diabetes is directly involved in oxidative stress production. Therefore, this work was conducted to investigate the histopathological changes which occur in parenchymatous and to evaluate the antioxidant effect of quercetin in alloxan induced diabetes in male albino rats.

Methods: Thirty-six male albino rats were divided into six groups of 6 rats in each group and treated as follows: a control group, quercetin group, diabetic control group, diabetic with quercetin group, diabetic with insulin group, diabetic with quercetin plus insulin group, alloxan was administered as a single dose (140 mg/kg body weight) to induce diabetes.

Results: Result showed histopathological changes which included degenerative to necrotic changes of the liver, kidney and pancreas and this are due to the effect of oxidative stress that occurred from diabetes by alloxan. Conversely, quercetin significantly modulated improved histopathological changes founded on this study with or without of insulin, furthermore, results showed that damaged tissues where improved when groups of rats treated with quercetin and insulin together.

Conclusions: It has been concluded that the quercetin could be promising antioxidants for reducing the risk of oxidation induced by diabetes that lead to nephrotoxicity, hepatotoxicity and pancreatic damage.
